Been a lurker here for some time. I recently purchased a One X from ebay in the UK, On receiving it I realised that it has a custom nexus styled jellybean ROM and won't pick up a signal with any sim card I use. Also I live in Ireland if that makes any difference. Unfortunately returning the phone isn't an option. I don't know if it had an EU rom or network branded one previously. I had a situation once like this in the past where I just ran the stock RUU on my old HTC sensation and it worked like a charm. Just not sure how to approach this one.

EDIT: The seller just mailed me to say that its originally T-Mobile network.
